Admittance measurements of the fabricated SBD were carried out in the bias voltage (V) range of -4 V and 6 V. Capacitance (C) and conductance (G/omega) measurements were carried out in a wide temperature range of 120-380 K so that temperature effects on electrical and dielectric properties of the SBD were investigated. Main electrical parameters were extracted from reverse bias C (-2)-V plots. It was found that variance of electrical and dielectric parameters of the SBD with temperature is basically different for low and high temperature regions. A fair number (similar to 10(12) eV(-1) cm(-2)) was obtained for surface states (N (ss)); however, N (ss) first decreased then increased with temperature. This result was associated with increased defects with temperature and higher activation energy in the high temperature region. Dielectric parameters of the SBD were also extracted and the dielectric constant of SBD was found as similar to 10 at room temperature. Application of modulus formalism to the admittance data revealed temperature-activated dielectric relaxation at 340 K. Results showed that the temperature has considerable effects on electrical and dielectric properties of Au/Bi4Ti3O12/n-Si SBD.en10.1007/s11664-016-5255-1info:eu-repo/semantics/closedAccessMFS Schottky barrier diodesbismuth titanateelectrical and dielectric propertiestemperature effectArticle46318951901WOS:000394212600056Q3Q3
